SHIPPING-REFRIGERATOR.

To all whom itmay concern:

Be it known that I, JACK citizen of the United States},3

ing to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in portable refrigerators and particularly toa type adapted for shipment on trains ortrucks to carry dry-chilled products such as poultry, game, etc;, which it is not desired shall come into actual contact with ice.

The principal object of the invention is to provide a refrigerator having a container or compartment for the goods being shipped which will have the chilling effect of the ice allaround it and which is so constructed that no ice or ice-water can get in and mix with the contents thereof, and in which a circulation of cold air is maintained thus preventing the stale, metallic taste and odor common in refrigerated articles.

I have also produced a refrigerator adapted to be returned to the point of ship-- ment and used again indefinitely. I v

Another object is to provide a light, simple and inexpensive device and yet one which will be exceedingly effective for thepurposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

On the drawings similar characters of reference indicate corresponding parts in the several views. 5

Figure 1 is a perspective elevation of improved refrigerator, with the cover of thecontainer removed.

Fig. 2 is a transverse cross section thereof showing the covers in place. 7

Fig. 3 is an enlarged fragmentary section showing the sides overlapping and the air vents formed thereby. V V

custom. A hinged lid 3 is provided on the box adapted to be fastened down in any suitable manner as by a haSp-lock 4. A

handle5 is provided on each end of the box,

Positioned in the box 1 and securedto the,

bottom thereof is a container 8, the same being spaced equally from the sides and ends of the box and with its sides and ends tapering somewhat in toward the top, pyra midwise. The .container is preferably constructed 1n.a substantial manner of some non-corrosive sheet metal such as zinc.

- The sides ofthe container are formed in two sections 9 and 10 longitudinally, the upper section 9 overlapping the lower section somewhat as at 1 1 andbeing spaced therefrom by spacer bars or blocks 11 to "form air vents 11 therebetween, at the same time preventing any ice from falling into the containerwhen ice is being packed therearound. The ends 12 of the container are slightly higher than the sides thereof but considerably lower than those of the box 1, and a cover or lid 13 is adapted to rest thereon, this lid extending beyond the plane of H the sides so that no ice can fall into the contamer through the air vents-lt formed by the sides being lower than the ends.

The bottom 15 of the container is spaced somewhat from the bottom of the outer box, the same resting on cleats 16 through which the container is secured to the box 1.

In operation, after the goods are placed in the container and the lid 13 placed thereon, ice is packed all around and over the same, and the lid 3 fastened down. As the ice melts and water forms, the same drips out through the drains 6, the space in the box 1 under the container always remaining cold whether ice or water is actually present out i The ing near the top, as that portion is naturally the warmest.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the object of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

, 1. A shipping refrigerator for dry chilled products comprising a box adapted for transportation and to containlice, a covered container secured in the box and spaced from the inner walls and bottom thereof, and means whereby a circulation of air is maintained between the interior of the container and the box through the sides thereof, but

secured in the box and spaced from the inner walls thereof, and means whereby a circulation of air is maintained between the interior of the container and the box, but ice is prevented from entering the container, such means including longitudinally and downwardly lapped sides on the container, such lapped portions being spaced from. each other, whereby air vents are formed, and a cover on the container projecting beyond the plane of the sides and being spaced there from to form a longitudinal slit on each .sides, such lapped portions being spaced from each other, whereby air vents are formed but ice is prevented from entering the container. I

In testimony whereof I aflix my signature in presence of two witnesses. r
